iFVS: Towards Instance-Optimized Filtered Vector Search
Abdullah Al-Mamun, Yeasir Rayhan, Walid G. Aref
Filtered vector search (FVS) is increasingly important in modern AI + DB systems, where vector similarity search is combined with relational predicates. Quantization plays a vital…
iPDB -- Optimizing Semantic SQL Queries
Udesh Kumarasinghe, Tyler Liu, Ahmed R. Mahmood +2
Structured Query Language (SQL) has remained the standard query language for databases. SQL is highly optimized for processing structured data laid out in relations. Meanwhile, in…
Towards a B+-tree with Fluctuation-Free Performance
Lu Xing, Walid G. Aref
Performance predictability is critical for modern DBMSs because index maintenance can trigger rare but severe I/O spikes. In a B or B+-tree with height H, node split propagation me…
Virtual-Memory Assisted Buffer Management In Tiered Memory
Yeasir Rayhan, Walid G. Aref
Tiered memory architectures have gained significant traction in the database community in recent years. In these architectures, the on-chip DRAM of the host processor is typically…
Gen-DBA: Generative Database Agents
Yeasir Rayhan, Walid G. Aref
Leveraging Machine Learning to optimize database systems, referred to as Machine Learning for Databases (ML4DB, for short), dates back to the early 1990s, spanning indexing techniq…
P-MOSS: Scheduling Main-Memory Indexes Over NUMA Servers Using Next Token Prediction
Yeasir Rayhan, Walid G. Aref
Ever since the Dennard scaling broke down in the early 2000s and the frequency of the CPUs stalled, vendors have started to increase the core count in each CPU chip at the expense…
